The invention provides a detachable traction system for track vehicles comprising a multiplicity of gripping bars each of which is bolted through a tread of a corresponding multiplicity of treads on each track of an endless track vehicle. The ice traction components include gripping bars each having a gripping surface comprising a patch of durable rough protrusive material. The mud or snow traction components include gripping bars each having a compression trough. In combination with the gripping bars being angled across their respective treads toward ensuring stability of steering and direction of travel of the vehicle, the tapering of the compression troughs reduces or eliminates clogging of the compression bars with mud or snow during travel thereby increasing performance through snowy, slushy, or semi-liquid terrain.

A cross-link for a track of a tracked vehicle, in particular a snow groomer, configured to advance along delicate ground, and which extends along a designated plane and has a mounting member comprising a wall configured for being arranged in contact with the delicate ground; a blade, which protrudes from the wall, is fixed to the wall and has a free edge, wherein the wall and the blade are configured so as to define two support surfaces extending on opposite sides of the blade to enable the sinking of the blade into the delicate ground and prevent the sinking of the mounting member.

A transverse bar for tracks of snow groomers is defined by a section bar, which extends in a direction, and is provided with an inner cavity, which extends through the section bar in the direction, is laterally open in the direction, and is at least partially filled with a water-repellent polymer filling material.

Support device for a tracked vehicle, in particular for a tracked vehicle configured for preparing ski slopes, wherein the tracked vehicle comprises a track comprising at least a first belt and a plurality of transverse metal elements, fixed to at least the first belt; a front wheel; and a rear wheel; the support device comprising at least a first plurality of support wheels configured to be arranged between the rear wheel and the front wheel inside the track, and a second belt closed in a loop and stretched around the plurality of support wheels and configured to be arranged inside the track; the support wheels and the second belt being shaped so as to provide a shape coupling, such as between an inner face of the second belt and an outer face of the support wheels; the second belt, such as an outer face of the second belt, being configured to be arranged in contact with an inner face of the track.

A belt for tracked vehicles suitable for being driven in a closed loop between a front wheel and a rear wheel of the vehicle along a longitudinal direction and for supporting a plurality of transverse bars adapted to stick in the ground along at least a portion of the lower run of the belt loop; the belt comprising a fabric multi-layer internal structure embedded in vulcanized rubber, wherein at least a portion of the fabric fiber of at least one layer is made of aramid.

A transverse bar for tracks of snow groomers is defined by a section bar and by covering plates fixed to the section bar, which is delimited by an outer surface and comprises a fixing portion to fix the transverse bar to the belts of a track of a snow groomer, and two lateral sides projecting from the fixing portion; the covering plates being arranged along the lateral sides so as to define part of an outer surface of the transverse bar.

A snowmobile track stud support includes a base configured to be coupled to a track of a snowmobile. A first boss extends from the base. The first boss includes a distal end having a boss aperture within which a stud can be disposed. A second boss extends from the base. The second boss includes a distal end with a boss aperture within which a stud can be disposed. A support flange extends from at least one of the first and second bosses and is disposed between the first and second bosses. The support flange includes a peak that projects away from the base. The distance from the peak to the base is greater than the distance from the distal end of the first boss to the base.

A tread link assembly is provided for improving the performance of a wheel on loose surfaces. The tread assembly includes a plurality of linked plates forming a circuit around the outer circumference of the wheel. The linked plates include first and second linking structures and releasable fasteners for linking adjacent plates together. The together the plates create a tread surface that is wider than the axial width of the wheel.

An endless track for use in propelling a snowmobile. The endless track extends between a first lateral side and a second lateral side and includes an inner drive surface and an outer ground-engaging surface. The inner drive surface includes a plurality of longitudinally spaced inner drive lugs used to drive and rotate the endless track. The outer ground-engaging surface includes a plurality of treads, where each tread extends continuous and uninterrupted along a constant height from the first lateral side to the second lateral side a full width of the endless track.

A vehicle track assembly includes a track framework including a frame structure, a drive drum, and a plurality of idler wheels supported by the frame structure. A drive track is arranged about and cooperatively engages the plurality of idler wheels and the drive drum. An adjustable ski is connected to the framework. The ski may extend forward of the track. An adjustable rearward extending ski may extend rearward of a track assembly. An indicator pole is coupled to the assembly to provide an indication of the angle of rotation of the assembly.
